Abstract
Methods of forming cutting elements for earth boring tools include providing a barrier material between a first powder and a second powder each comprising diamond grains, and subjecting the powders and barrier material to high temperature and high pressure conditions to form polycrystalline diamond material. The formation of the polycrystalline diamond material is catalyzed, and catalytic material may be hindered from migrating across the layer of barrier material. Cutting elements for use in earth boring tools include a barrier material disposed between a first layer of polycrystalline diamond material and a second layer of polycrystalline diamond material. Earth boring tools include one or more such cutting elements for cutting an earth formation.
